Web17 mrt. 2010 · For power, a leading power factor indicates a negative value of theta. If you look at the NCEES solution to #517, the angle for the synchronous motor is -45.6o. You can have it exactly backwards and still get the right answer for #517 because it's not directly asking for the sign of the angle.
